[0042] In an embodiment, the first information is wake-up information, and the second information is determined according to signaling.

[0043] The signaling is configured as whether to transmit the second information.

[0044] The second information includes one of the following: subgroup wake-up information, first information, cell index information, terminal index information, PO information, PF, information carried on a PEI, or a number of groups corresponding to the second information.

[0045] In an embodiment, the first information also includes Z1-bit CRC information, and the second information also includes Z2-bit CRC information, where Z1 and Z2 are each an integer greater than or equal to 0.

[0046] In the following embodiments, by way of example, the first communication node is a base station, and the second communication node is a terminal.Embodiment one

[0047] The base station determines first information and second information, preprocesses the first information, and sends the preprocessed first information using on-off keying (OOK) modulation. The second information is carried, in the form of sequence, on OOK symbols.

[0048] In an embodiment, it is assumed that the wake-up information to be sent is 8-bit wake-up information 01010011, it is assumed that the CRC check sequence is 11011001, and it is assumed that the sequence set includes 4 sequences, that is, at most 2 bits of information can be carried on each OOK symbol. Table 1 lists the mapping relationship between information and sequences. It is assumed that all OOK symbols carry the same information. Table 1 Mapping relationship between information and sequencesInformationSequence001012103114

[0049] The base station determines, according to the information carrying manner of the information carried on the OOK symbols and the size of the information carried on the OOK symbols, that the length corresponding to the first information is 14 bits and the length corresponding to the second information is 2 bits. The base station concatenates 8-bit group wake-up information and CRC information and divides the concatenated information into the first information and the second information according to a predefined rule. In an example, the first information is the first 14 bits of the concatenated information, and the second information is the last 2 bits of the concatenated information. The base station preprocesses the first information using Manchester coding with a code rate of 1 / 2 (where 0 is encoded as 01 and 1 is encoded as 10) and sends the preprocessed first information using OOK modulation. Sequences selected according to the second information are carried on corresponding OOK symbols.

[0050] The terminal obtains the first information based on the first length of 14 bits and obtains the second information based on the second length of 2 bits, concatenates the first information and the second information to obtain 8-bit group wake-up information and CRC information, and, if the CRC check is passed, determines whether to start data transmission according to the corresponding wake-up information.Embodiment two

[0051] It is assumed that the wake-up information to be sent is 8-bit wake-up information 01010011. It is assumed that the CRC check sequence is 11011001. It is assumed that the sequence set includes 4 sequences. That is, at most 2 bits of information can be carried on each OOK symbol. It is assumed that different OOK symbols carry different information.

[0052] The base station determines, according to the information carrying manner of the information carried on the OOK symbols and the size of the information carried on the OOK symbols, that the length corresponding to the first information is 6 bits. Each OOK symbol carries 2 bits of information, and OOK modulation carries 1 bit of information; therefore, the length of the first information is obtained by dividing the length of all information to be sent by (2+1) and rounding up the result. The length of the second information is 10 bits. The base station concatenates 8-bit group wake-up information and 8-bit CRC information and divides the concatenated information into the first information and the second information according to a predefined rule. In an example, the first information is the first 6 bits 010100, and the second information is the last 10 bits 1111011011. The base station preprocesses the first information using Manchester coding with a code rate of 1 / 2 and sends the preprocessed first information using OOK modulation. In the second information, corresponding sequences are selected in units of 2 bits and carried on corresponding OOK symbols.

[0053] FIG. 3 is a diagram illustrating that second information is carried on symbols corresponding to a first modulation according to an embodiment. As shown in FIG. 3, since 10 / 2 = 5, sequences are carried on only five "1" symbols (assuming that the first position corresponds to a "1" symbol). The first five symbols may be selected to carry the sequences; or the last five symbols may be selected to carry the sequences; or the last symbol may repeat the first symbol or the second-to-last symbol, and so on.

[0054] In another example, since each OOK symbol carries 2 bits of information and OOK modulation carries 1 bit of information, the 16 bits are divided into six pairs in units of three bits. The first bits in these pairs constitute the first information. The remaining two bits in these pairs constitute the second information. That is, the bit sequence 0101001111011001 is divided into six pairs in units of three bits as 010, 100, 111, 101, 100, and 1. Accordingly, the first information is 011110, and the second information is 1000110100.Embodiment three

[0055] It is assumed that the wake-up information to be sent is 8-bit wake-up information 01010011. It is assumed that the CRC check sequence is 11011001. It is assumed that the sequence set includes 4 sequences. That is, at most 2 bits of information can be carried on each OOK symbol. It is assumed that OOK symbols are grouped by N OOK symbols per group (where the OOK symbols here refer to symbols corresponding to the first position). The same group carries the same information. Different groups carry different information. It is assumed that N = 2. The value of N may be fixed or configured through signaling. It is assumed that the first position corresponds to a "1" symbol.

[0056] The base station determines, according to the information carrying manner of the information carried on the OOK symbols and the size of the information carried on the OOK symbols, that the length corresponding to the first information is 8 bits. Each two OOK symbols carry 2 bits of information, and OOK modulation carries 1 bit of information; therefore, the length of the first information is obtained by dividing the length of all information to be sent by (2+2)*2 and rounding up the result. The length of the second information is 8 bits. The base station concatenates 8-bit group wake-up information and 8-bit CRC information and divides the concatenated information into the first information and the second information according to a predefined rule. FIG. 4 is a diagram illustrating that second information is carried on symbols corresponding to a first modulation according to an embodiment. In an example, the first information is the first 8 bits 01010011, and the second information is the last 8 bits 11011011. The base station preprocesses the first information using Manchester coding with a code rate of 1 / 2 and sends the preprocessed first information using OOK modulation. In the second information, corresponding sequences are selected in units of 2 bits and carried on corresponding OOK symbols. Each two "1" symbols carry the same information.Embodiment four

[0057] It is assumed that the wake-up information to be sent is 9-bit wake-up information 010100111. The wake-up information corresponds to 3 group indexes to be woken up. It is assumed that the sequence set includes 4 sequences, that is, at most 2 bits of information can be carried on each OOK symbol. It is assumed that different OOK symbols carry different information.

[0058] The base station determines, according to the mapping manner of group wake-up, that the first information is high bits of each of group indexes and the second information is low bits of each of the group indexes, preprocesses the first information using Manchester coding with a code rate of 1 / 2, and sends the preprocessed first information using OOK modulation. Corresponding sequences are selected in units of two bits from the second information and carried on OOK symbols.

[0059] Since each OOK symbol can carry up to 2 bits of information, the low 2 bits of each of the group indexes are determined as the second information. Accordingly, the first information is 011, and the second information is 100011.

[0060] The terminal determines that the first information includes at least high 1 bit of each of the group indexes and the second information includes at least low 2 bits of each of the group indexes. Since the received first information is 011 and the received second information is 100011, the wake-up information 010100111 is obtained, and whether data transmission is performed is determined according to the wake-up information.Embodiment five

[0061] It is assumed that the wake-up information to be sent is 8-bit wake-up information 01010011. It is assumed that the sequence set includes 4 sequences. That is, at most 2 bits of information can be carried on each OOK symbol.

[0062] The wake-up information is divided into M groups. By way of example, M = 2. That is, 0101 forms a group, and 0011 forms a group. The base station determines that the first information is high 2 bits of each of group indexes and the second information is low 2 bits of each of the group indexes, preprocesses the first information 0100 using Manchester coding with a code rate of 1 / 2, and sends the preprocessed first information using OOK modulation. Corresponding sequences are selected in units of two bits from the second information and carried on OOK symbols. FIG. 5 is a diagram illustrating that second information is carried on symbols corresponding to a first modulation according to an embodiment. After encoding, the first information is 01100110. Sequence 1 selected according to 00 is carried on the first two "1" symbols. Sequence 4 selected according to 11 is carried on the last two "11" symbols.

[0063] The terminal determines that the first information includes at least a first part of the wake-up information and the second information includes at least a second part of the wake-up information. Since the received first information is 0101 and the received second information is 0011, the wake-up information 010100111 is obtained, and whether data transmission is performed is determined according to the wake-up information.Embodiment six

[0064] It is assumed that the wake-up information to be sent is 8-bit wake-up information 01010011. It is assumed that the CRC check sequence is 11011001. It is assumed that the sequence set includes 4 sequences. That is, at most 2 bits of information can be carried on each OOK symbol.

[0065] The base station determines, according to the information type, that the first information is wake-up information and the second information is CRC information, preprocesses the first information using Manchester coding with a code rate of 1 / 2, and sends the preprocessed first information using OOK modulation. Corresponding sequences are selected in units of two bits from the second information and carried on OOK symbols. FIG. 6 is a diagram illustrating that second information is carried on symbols corresponding to a first modulation according to an embodiment. Since the first information, after encoding, contains eight "1" symbols, the second information can be carried in a repeated manner. One repetition manner is to repeat after all the information has been mapped once. For example, as shown in the figure, the sequences 4, 2, 3, and 2 are mapped for the first time and then mapped once again. It is to be understood that the repetition manner shown in the figure is an example. Alternatively, a single sequence may be repeatedly mapped before traversing all sequences, for example, mapping the sequences in the order of sequence 4, sequence 4, sequence 2, sequence 2, sequence 3, sequence 3, sequence 2, and sequence 2 onto the "1" symbols.

[0066] The terminal determines that the first information is wake-up information and the second information is a CRC check. Since the received first information is 01010011 and the received second information is 11011001, the wake-up information 010100111 is obtained, and whether data transmission is performed is determined according to the wake-up information.Embodiment seven

[0067] It is assumed that the wake-up information to be sent is 8-bit wake-up information 01010011. It is assumed that the CRC check sequence is 11011001. It is assumed that the sequence set includes 4 sequences. That is, at most 2 bits of information can be carried on each OOK symbol. The following table lists the mapping relationship between information and sequences.

[0068] The base station determines that the first information is 4-bit wake-up information plus a 4-bit CRC check and the second information is 4-bit wake-up information plus a 4-bit CRC check. The base station preprocesses the first information using Manchester coding with a code rate of 1 / 2 and sends the preprocessed first information using OOK modulation. Corresponding sequences are selected in units of two bits from the second information and carried on OOK symbols.

[0069] In an example, the 4-bit wake-up information in the first information is the first 4 bits of the wake-up information, and the 4-bit wake-up information in the second information is the last 4 bits of the wake-up information.

[0070] In an example, the 4-bit wake-up information in the first information is the last 4 bits of the wake-up information, and the 4-bit wake-up information in the second information is the first 4 bits of the wake-up information.

[0071] In an example, the first information and the second information are determined according to a time-frequency position in which sending is performed.

[0072] The terminal determines that the first information is 4-bit wake-up information plus a 4-bit CRC check and the second information is 4-bit wake-up information plus a 4-bit CRC check and determines, according to the received first information and the received second information, whether to perform data transmission.Embodiment eight

[0073] It is assumed that the wake-up information to be sent is 8-bit wake-up information 01010011. It is assumed that the CRC check sequence is 11011001. It is assumed that the sequence set includes 4 sequences. That is, at most 2 bits of information can be carried on each OOK symbol.

[0074] The base station determines that the first information is 4-bit wake-up information plus an 8-bit CRC check and the second information is 4-bit wake-up information plus an 8-bit CRC check. The base station preprocesses the first information using Manchester coding with a code rate of 1 / 2 and sends the preprocessed first information using OOK modulation. Corresponding sequences are selected in units of two bits from the second information and carried on OOK symbols.

[0075] The terminal determines that the first information is 4-bit wake-up information plus an 8-bit CRC check and the second information is 4-bit wake-up information plus an 8-bit CRC check and determines, according to the received first information and the received second information, whether to perform data transmission.Embodiment nine

[0076] It is assumed that the wake-up information to be sent is 8-bit wake-up information 01010011. It is assumed that the CRC check sequence is 11011001.
